The VS6 series is an open-loop version of a low-voltage cylindrical piezoelectric ceramic actuator that has undergone special design modifications based on conventional piezoelectric actuator designs. Unlike conventional piezoelectric actuators, the VS6 series does not have mechanical interfaces, and the commonly used thread fixation is abandoned for bottom fixation. Instead, it is fixed by direct placement or positioning with auxiliary components, and designed to lead out the sheath and lead from the side. This series of actuators has a very compact appearance and is very suitable for use in space efficient environments.
